Description

Technical Field

[0001] This utility model relates to the technical field of automatic feeding devices, and specifically to a welding stud feeding device. Background Technology

[0002] In the construction of buildings and bridges, steel structures and reinforced concrete structures typically have a large number of shear connectors, also known as shear studs, T-studs, or cylindrical head studs, installed on the surface of the steel structure. These studs are welded and fixed to the steel beams, columns, and other steel structures.

[0003] Traditionally, welding studs are picked up manually and welding is completed manually. However, due to the large number of studs, manual operation is inefficient. To address this, a prior Chinese patent (authorization announcement number CN205437447U, utility model name: A device for automatically feeding T-shaped welding studs) discloses an automatic feeding device for T-shaped welding studs. This device includes a hopper, a feeding plate, a guide rail, and a drive mechanism. The hopper has an opening slot, and the feeding plate is positioned within this slot. The front end of the feeding plate is rotatably connected to the front end of the hopper, while the rear end is a free-moving end. The lower part of the feeding plate is connected to the drive mechanism, and the top of the feeding plate has a feeding groove. The guide rail is inclined at the front end of the hopper and aligns with the outlet of the feeding groove. The drive mechanism rotates the feeding plate, allowing the T-shaped welding studs in the hopper to enter the feeding groove and then slide into the guide rail for transport. Because the guide rail connects to the side opening of the hopper, when the T-shaped welding stud is placed laterally on the feeding slot, it can slide out of the side opening of the hopper, causing material to fall out. Therefore, a new solution is needed for feeding the welding stud. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a welding nail feeding device to solve the problem of easy material drop in the existing feeding device.

[0011] A first drive mechanism is provided on the frame and driven to the lower part of the feeding plate. The first drive mechanism can drive the feeding plate to swing up and down relative to the feeding hopper. When the feeding plate swings down, the welding nails in the feeding hopper can enter the guide groove. When the feeding plate swings up to an inclined position, the guide groove is connected to the linear vibration conveying mechanism, so that the welding nails in the guide groove can slide into the linear vibration conveying mechanism.

[0012] A movable and adjustable push plate is mounted on the frame. The push plate is located at the top of the linear vibrating conveyor and blocks the outside of the side opening. The direction of movement adjustment of the push plate is consistent with the transmission direction of the linear vibrating conveyor. By adjusting the movement of the push plate, excess welding studs on the linear vibrating conveyor can be pushed back into the feeding hopper.

[0016] A further improvement of the welding stud feeding device of this utility model is that it also includes a second driving mechanism disposed on the frame and connected to the push plate. The second driving mechanism can drive the push plate to move back and forth along the moving adjustment direction.

[0017] A further improvement of the welding stud feeding device of this utility model is that the second driving mechanism includes a second telescopic driving member disposed on the frame. The setting direction of the second telescopic driving member is consistent with the moving adjustment direction of the push plate. The second telescopic driving member is connected to the push plate, and the push plate is moved and adjusted by the telescopic adjustment of the second telescopic driving member.

[0018] A further improvement of the welding stud feeding device of this utility model is that the second driving mechanism includes a motor mounted on the frame, a lever connected to the motor shaft on the motor, and a telescopic rod mounted on the frame and corresponding to the push plate;

[0019] The telescopic rod is telescopic and adjustable, and the direction in which the telescopic rod is set is consistent with the direction of movement adjustment of the push plate. The end of the telescopic rod is connected to the push plate.

[0021] The lever is movably connected to the drive shaft;

[0022] The motor can drive the lever to swing back and forth, and the lever, through the drive shaft, drives the telescopic rod to extend and retract, thereby enabling the push plate to move and adjust.

[0024] A further improvement of the welding stud feeding device of this utility model is that the driving end of the second driving mechanism is provided with a mounting base;

[0025] The middle part of the push plate is rotatably mounted on the mounting base.

[0026] A further improvement of the welding stud feeding device of this utility model is that the lower part of the push plate has an upwardly recessed groove, and the push plate is fitted onto the linear vibration conveying mechanism through the groove.

[0028] The beneficial effects of this utility model welding stud feeding device are:

[0029] The welding stud feeding device of this utility model has a movable and adjustable push plate installed at the side opening, which allows vertically arranged welding studs to pass through, while horizontally arranged welding studs are pushed back into the feeding hopper. This realizes the pushing back of excess welding studs, avoids the phenomenon of welding studs falling out, and also avoids jamming during the welding stud feeding process.

[0033] Figure 3 This is a side view of the welding stud feeding device of this utility model. Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] See Figure 1 This invention provides a welding stud feeding device for automatic welding stud feeding, which also solves the problem of stud dropping in traditional feeding devices. The welding stud feeding device of this invention guides the welding studs by a feeding plate that swings up and down within the feeding hopper, allowing the studs to slide vertically into the guide groove of the feeding plate, and then into a linear vibrating conveyor mechanism. The linear vibrating conveyor mechanism then transports the welding studs forward to complete the feeding operation. This invention also features a reciprocating push plate at the side opening of the feeding hopper. This push plate can push excess welding studs (such as those sliding laterally on the top of the feeding plate) back into the feeding hopper, preventing both stud dropping and jamming. The welding stud feeding device of this invention will be described below with reference to the accompanying drawings.

[0036] See Figure 1 This diagram shows a three-dimensional structural schematic of the welding stud feeding device of this utility model. (See attached diagram.) Figure 2 , showed Figure 1 A magnified view of a portion of point A in the middle. (See below for reference.) Figure 1 and Figure 2 The present invention describes the welding stud feeding device.

[0037] like Figure 1 and Figure 2As shown, the welding stud feeding device of this utility model includes a frame 21, a feeding hopper 22, a linear vibrating conveyor mechanism 23, a feeding plate 24, a first drive mechanism 25, and a push plate 26. The feeding hopper 22 is mounted on the frame 21. The feeding hopper 22 has a top opening 221 and an internal space for storing welding studs 11. The side of the feeding hopper 22 has a side opening 222, and the bottom of the feeding hopper 22 has a slot. When feeding welding studs 11, the welding studs can be... 11 is poured into the feeding hopper 22 through the top opening 221; a linear vibrating conveyor 23 is mounted on the frame 21, and part of the linear vibrating conveyor 23 extends into the feeding hopper 22 through the side opening 222; a feeding plate 24 passes through the slot and is partially located in the feeding hopper 22, and the top of the feeding plate 24 is provided with a guide groove 241, the width of which is greater than the diameter of the rod of the welding stud 11 and smaller than the diameter of the head of the welding stud 11; the lower part of the feeding plate 24 has a portion Located on the outside of the slot of the feeding hopper 22; the first drive mechanism 25 is mounted on the frame 21 and is driven to the lower part of the feeding plate 24. The first drive mechanism 25 can drive the feeding plate 24 to swing up and down relative to the feeding hopper 22. When the feeding plate 24 swings down, the welding nails 11 in the feeding hopper 22 can enter the guide groove 241. When the feeding plate 24 swings up to an inclined position, the guide groove 241 is connected to the linear vibration conveying mechanism 23, so that the welding nails 11 in the guide groove 241 can slide into the linear vibration conveying mechanism 23; the push plate 26 is mounted on the frame 21 and is movable and adjustable. The push plate 26 is located at the top of the linear vibration conveying mechanism 23 and is blocked on the outside of the side opening 222. The moving adjustment direction of the push plate 26 is parallel to the transmission direction of the linear vibration conveying mechanism 23. By moving and adjusting the push plate 26, excess welding nails 11 can be pushed back into the feeding hopper 22.

[0038] The feeding principle of this welding stud feeding device is as follows:

[0039] The welding studs 11 to be fed are poured into the feeding hopper 22. Then, the first drive mechanism 25 is activated to drive the feeding plate 24 to swing up and down. When the feeding plate 24 swings downward, the guide groove 241 at the top of the feeding plate 24 moves towards the groove at the bottom of the feeding hopper 22. In this way, the welding studs 11 in the feeding hopper 22 can slide into the guide groove 241. Under normal circumstances, the rod of the welding stud 11 is vertically inserted into the guide groove 241, and the head of the welding stud 11 is located on the outside of the guide groove 241. When the feeding plate 24 swings upward to the position, the guide groove 241 is inclined. The end of the guide groove 241 near the side opening 222 is connected to the end of the linear vibrating conveyor 23. The height of the end of the guide groove 241 near the side opening 222 is lower than the height of the other end. In this way, the welding studs 11 in the guide groove 241 can slide vertically into the linear vibrating conveyor 23. The linear vibrating conveyor 23 transmits the welding studs 11 forward one by one through vibration. During the upward swing of the feeding plate 24, welding nails 11 may be placed horizontally on the guide groove 241 and then slide horizontally into the linear vibrating conveyor mechanism 23. To prevent the welding nails 11 from sliding out of the feeding hopper in a horizontal state, the push plate 26 moves back and forth at the side opening 222 at the same time as the first drive mechanism 25 is started. When a horizontal welding nail 11 slides over, the push plate 26 can push it back into the feeding hopper 22. When a vertical welding nail 11 slides over, the push plate 26 can let the vertical welding nail 11 pass through, thus pushing the non-vertically fed welding nails back into the feeding hopper 22 and avoiding material drop and subsequent jamming.

[0040] In one specific embodiment of this utility model, such as Figures 1 to 3 As shown, the first drive mechanism 25 includes a first telescopic drive member 251 mounted on the frame 21 and a drive link 252 mounted on the frame 21 with one end rotatable. The other end of the drive link 252 is connected to the lower part of the feed plate 24. The first telescopic drive member 251 is inclined and drives the drive link 252 to swing up and down through telescopic adjustment, thereby driving the link 252 to swing up and down with the feed plate 24.

[0041] Furthermore, one end of the drive linkage 252 is rotatably mounted on the corresponding part of the frame 21 via the connecting shaft 253.

The end of the telescopic rod 273 is connected to the push plate 26. A drive shaft 274 is connected to the telescopic rod 273. The lever 272 is movably connected to the drive shaft 274. The motor 271 can drive the lever 272 to swing back and forth, thereby the lever 272 drives the telescopic rod 273 to extend and retract via the drive shaft 274, thus realizing the movement adjustment of the push plate 26.

[0047] Furthermore, the end of the lever 272 away from the motor 271 is provided with a strip groove 2721, and the lever 272 is fitted onto the drive shaft 274 through the strip groove 2721.

[0048] Furthermore, a mounting plate 211 is provided on the frame 21 corresponding to the telescopic rod 274 of the second drive mechanism 27. The mounting plate 211 is provided with a positioning block 212, and the positioning block 212 is provided with a positioning groove. Part of the telescopic rod 273 is inserted into the positioning groove, so that the telescopic rod 273 can be extended and retracted along the positioning groove.

[0049] Preferably, the telescopic rod 273 includes a first rod body and a second rod body that are sleeved together.
